Abstract: In scattering experiments with synchrotron radiation, photon counting detectors suffer both counting coincidence and extreme high data transfer rates to the digital store. With an integrating detector, however, these problems can be overcome by buffering the high incoming photon flux in an analogue store. After conversion to a number of electrons in a first step for a given time interval, the number of incoming photons is integrated into a fast analogue store as an increasing electrical charge. In the second step, the contents of this analogue store is read out, digitized and finally processed by a digital data aquisition to get the number of detected photons for each resolution element. The X-ray detector was built with a commercially manufactured SEC vidicon. The output window of the vidicon was coupled via demagnifying fiber optic cone to the output window of a commercially manufactured Varain image intensifier tube. This was then coupled to a Gd$_{2}$O$_{2}$S fluorescence screen. To show the function of the integrating X-ray detector typical small angle scattering experiments was made. Also a new readout technique for measurements of high-contrast, high-flux X-ray patters has been developed and was used in measurements with a silica aerogel.
